Product Introduction

TBW series intelligent universal circuit breakers (hereinafter referred to as circuit breakers) are suitable for the distribution network with 50Hz AC, 400V-690V rated voltage, and 200-6300A rated current. They are used to distribute electrical energy, protect circuits, power equipment, and motors from overload, undervoltage, short circuit, single-phase grounding, and other hazards. The circuit breakers can be equipped with various intelligent controllers, with complete protection functions to improve the reliability of power supply. The communication type intelligent controller is equipped with a communication interface for easy connection with the field bus. It can achieve the “four remote” functions of telemetry, remote adjustment, remote control, and remote signaling, meeting the requirements of control automation. Leakage transformers and corresponding intelligent controllers are also configured to achieve leakage protection. This circuit breaker is widely used in power stations, factories, mines, and modern high-rise buildings, especially in the distribution system of intelligent buildings.
